Definitions

  • a meandering cut edge is produced in the web-shaped raw material, which means that during a single cutting operation, based on a certain rotation angle, a first meandering cut edge is attached to the front edge of the web-shaped raw material and that in axial distance from the first meandering (zig-zag) cutting edge a second meandering cut edge is applied in the raw material, which is laid to the first cutting edge, that the second cutting edge reaches a complete separation of located in a transverse axis of the raw material web Schneidgutschnipseln.
  • two mutually offset transverse axes are defined, wherein the two transverse axes are arranged offset from one another by a certain longitudinal spacing of the raw material (in the direction of passage). It is important now that in the area of the first transverse axis precisely defined snippets are cut out in a cutting process, these snippets occupy a lateral distance from each other, but lie on the same transverse axis.
  • the cutting plates of the first cutting bar are offset from one another in the axial direction relative to the cutting plates of the second cutting bar.
  • stator knife it is preferred in this case if a single stator knife is arranged stationary, because it is not necessary according to the functional principle of the invention to provide a plurality of stator knives, as required by the prior art.
  • the cutting rotor 12 has at least two cutting edge strips arranged on different radius lines.
  • the one cutting inserts of the outer cutting edge strip are designated by 25, while the inner cutting inserts located radially inward on the second cutting edge strip are denoted by 26.
  • FIG. 5 shows, moreover, that the cutting plates 25 in aligned extension of the guide profiles 29 on a same transverse axis 41 (see FIG. 9 ), while radially rearwardly offset the inner cutting plates 26 on a second transverse axis 42 (see FIG. 9 ) are arranged.
  • FIGS. 6 to 8 show the succession of cuts, which are mounted in the web-like raw material 3 in the same cutting process.
  • FIG. 6 only shows the type and arrangement of the web-shaped raw material just before attachment of the cut.
  • the outer, located on the first radius line cutting plates 25 and located on the second radius line inner cutting plates 26 are in the same plane.
  • the two cutting plate planes with respect to the outer cutting plates 25 and the inner cutting plates 26 may also be offset from one another. That is, the two cutting edge strips with the cutting plates 25 and 26 would then be arranged offset by an arbitrary circumferential angle in the range of 360 degrees to each other.
  • FIG. 9 shows the top view of the front end of a web-shaped raw material 3, which is supplied to the cutting rotor 12 in the direction of arrow 4.
  • a meandering cut edge 38 is thus defined, wherein the cut edges 34, 35, 36 are each offset at an angle of 90 degrees to one another.
